Alcoa hits out over LME policy changes
Aluminium producer says the exchange's 'irresponsible' move to overhaul warehousing has led to confusion and a drop in premiums

Global aluminium premiums have fallen because of "confusion" over the London Metal Exchange's proposal to overhaul its warehousing policy, Alcoa chief financial officer William Oplinger said.

The comments came as Alcoa chairman and chief executive Klaus Kleinfeld lashed out at the LME's latest proposal to solve a year-long crisis that has damaged the exchange's reputation and cost industrial users billions of dollars in additional expenses.
Kleinfeld said the LME was "very irresponsible" by going public with its proposal without consulting the industry first.
Hong Kong Exchanges and Clearing bought the LME in June last year.
Alcoa's comments came after the aluminium producer reported better-than-expected third-quarter results as cost-cutting efforts offset weak LME prices.
